Whenever that moment arrives to change your old smartphone for a new one or simply when you decide to buy your first smartphone, one of the first questions that assail us is what kind of camera should we choose to maintain a good quality price. In order to solve this situation we will show in this small guide what to look for when choosing the camera of a smartphone .

First of all we must break that legend that tells us that the more megapixels the better the camera will be. This is not true, since megapixels are only indicators of the size of the photo . The more megapixels, the larger the photo will be.

To have a larger size, we are only interested in zooming or making cuts of the photograph taken and not losing resolution so quickly.

As the destination of use of our photos is usually the smartphone screen itself or the screen of a computer, having many megapixels is not something that helps us improve the quality . For example in a Full HD resolution, the resolution is 1920 × 1080 pixels which are 2 megapixels. Having a photo with a larger size on a screen of this type would not imply better quality, since it has to adjust to the available resolution.

Once the issue of megapixels has been clarified, we turn to other important aspects to be considered:

• Aperture : directly influences the amount of light that the camera is able to capture. This value is indicated with the code f / xx, for example f / 2.0. The lower this value is better, for example, the current high-end cameras offer values ​​f / 2.0 and f / 2.2.
• Sensor size : it is responsible for collecting light, therefore the larger its surface, the better quality in the photos. This data is usually given in units "μm per pixel" and the larger the better. As an example, the Google Pixel has a sensor size of 1.55 μm per pixel.
• Focus speed : a photo would lose all its interest if the focus was not fast and gave us a clear picture.
